Question

find diameter of area is 3.8 CM²​

Answer 1

Area of the circle is given to be 3.8 cm²​

We have to find the diameter.

So first, by using the formula of area of the circle we will find the radius

Area = πr²

3.8   = 3.14 × r²

    r² = 3.8 / 3.14

    r² = 1.21

     r = 1.1 cm

Now, we know that diameter is always double the radius

Diameter = 2 × radius

               = 2 × 1.1

               =2.2 cm

Hence, the diameter will be 2.2 cm
